PATENT OFFICE.

SPECIFICATION forming part of Letters Patent No. 351,151, dated October 19, 1886.

(No model.)

To aZZ whom it may concern.-

Be it known that 1, ROBERT BEACHMAN, of Lyons, in the county of lV-ayne and State of New York, have invented a certain new and useful Improvement in Vises; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this application.

My improvement relates to that class of upright Vises in which a nut turns 011 a screw to force the jaws together.

My invention consists of a vise in which the movable jaw is constructed with a flanged arm cast solid with it, the edges of the flanges being formed with teeth that have the lead of a screw-thread and answer the purpose of a common screw, at the same time holding the jaw in position to meet the stationary jaw without other parts.

It also consists in the combination, with the stationary jaw, of a movable jaw provided with a flanged arm having teeth on its edges, said movable jaw extending below the stationary jaw, and having mounted in its lower end a drill capable of being used below the stationary jaw or at the top by simply inverting the movable jaw.

It also consists of the combination of the movable jaw, the flanged arm, an independent follower, and a nut, all as hereinafter described.

In the drawings, Figure 1 is a perspective View of the vise. Fig. 2 is a side elevation of the movable jaw removed from place, inverted or turned bottom upward, and provided with a follower for converting it into an independent drill. Fi g. 3 is a cross-section of the flanged arm.

A is the stationary jaw; B, the movable one.

My improvementis as follows:

The movable jaw B is made with a horizontally-pr0jectiug arm, 0, that forms a solid part of it. The arm consists of right angled flanges a a a a, united by a central web, as shown in the cross-section Fig. 3, and on the edges of these flanges are cut a series of teeth, b b, which have the lead of a screwthread, so that when a nut is turned thereon it will have the same progressive action that it has on a full screw. A corresponding slot, f, is made through the other jaw, A, through-which the arm slides freely.

D is a nut with polygonal sides, that screws on the arm, and E is an opensided wrench, which fits over the nut, and by which it is turned. By turning up the nut the movable jaw will be forced in to clamp any article against the stationary jaw, and by turning it back the jaws can be separated.

The great advantage of this construction is that the arm 0 is formed integral and solid with the movable jaw, and can be cast so that it is very cheap 5 and, furthermore, the flanged form of the arm makes it a complete guide to the movable jaw, so that it will not-tilt nor twist sidewise, but will come up square to the other jaw, and no side or bottom guides are necessary to keep it in the upright position, as are required where a common cylindrical screw is used, which cannot be madefast to the movable jaw, but must turn in it. Aside from this,

there is less friction on the nut than where a full screw is used, and it is quite as effective in use.

If desired, a portion only of the flanges may be toothedfihe others being left blank, asshown in Fig. 3.

The movablejaw B projects below the arm 0 a distance equal to the projection above, and in its lower end is mounted a drill, F, operated by a crank, I. The drill in this case comes below the stationary jaw and operates on any article placed against the support on which the stationaryjawis placed. It is therefore entirely out of the way of the jaws in clamping any article between them; but whenever desired the drill can be brought to the top and be made to act on any article between the jaws by simply drawing the arm 0 from the stationary jaw, inverting the movable jaw, and replacing the arm again. The equal projection of both ends of the movable jaw beyond the center arm allows this to be done. By this construction, also, the movable j aw can be detached and used as an independent borer, 5

can be used in places where the same attachment on a vise could not.

Having described my invention, what I claim as new, and dcsireto secure by Letters 5 Patent, is-

1. In a vise, the combination of stationary and movable jaws, the movable jaw being constructed with an arm cast solid with it, said arm being flanged and provided with teeth on 10 its edges, and the stationary jaw being provided with a corresponding slot, through which the arm runs, as shown and described, and for the purpose specified.

2. In a vise, the combination of stationary 15 and movable jaws, the movable jaw provided with a flanged arm and extending below the arm,and provided with a drill in its lower end, as'herein shown and described. 1

3. The combination, with the movable jaw provided with the flanged arm 0, ofthe fol- 20 lower H and nut D, as shown and described, and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
